Parameter
Value Function
Flow display
Display of flow and possible output.
No
The function is not available.
Flowing
Shows supply air and extract air flow (depending on what is activated).
Analogue inputs are activated unless they have been activated via the fan regulation setting.
Fan step type
Necessary fan regulation output that concerns settings for Fan regulation type, Timing program step
and Dig.step freq.conv.
Separate
Digital output for each step.
Example:
Fan regulation type = Direct / Timing program step = 2 / Extract air fan = Yes
---> 4 digital outputs: 2 each for step 1 and step 2, separated for supply air and extract air fans.
Sep.Comb.
Separate outputs for the first step, common outputs for subsequent steps.
Example:
Fan regulation type = Pressure reg. / Timing program function = Step+Temp / Timing program step =
3 / Extract air fan = Yes / Dig.step freq.conv = 3.
---> 4 digital outputs: Step 1 as separate activation of frequency-regulated fans, two extra outputs
that can be used (Dig.step freq.conv) for step 2 and step 3.
Binary
The outputs for steps are binarily coded. The setting can be used for Fan regulation type = Direct or
Dir.fro.
Example:
Fan regulation type = Direct / Timing program function = Step+Temp / Timing program step =
3 / Extract air fan = Yes
---> 4 digital outputs: 2 digital outputs each per fan (Step 1 = DO1 TRUE, Step 2 = DO2 TRUE,
Step 3 = DO1 and DO2 TRUE).
Fan alarm
Inputs for fan alarm (e.g. thermojunction). Logical 1 = alarm.
No
No alarm.
Comb.
Digital input for common alarm.
Supply air
Digital input for supply air fan alarm.
Extract air
Digital input for extract air fan alarm.
Extract
Two digital inputs for supply air and extract air fan alarms.
Fan return
Inputs for operating messages from fans (e.g. pressure current guard or relay contact).
Logical 1 = activated fan.
No
No return.
Comb.
Digital input for common operating messages.
Supply air
Digital input for operating messages for supply air fan.
Extract air
Digital input for operating messages for extract air fan.
Extract
Two digital inputs for operating messages for supply air and extract air fans.
Fan deviation alarm
Setpoint or actual value for monitoring pressure or flow. The alarm is triggered in the event of
a deviation that remains for a certain period of time.
No
No monitoring
Supply air
Monitoring of supply air only.
Extract air
Monitoring of extract air only.
Extract
Monitoring of supply and extract air.
Room temp. fan
comp.
No
Room temperature-dependent fan compensation.
Precondition: Room or extract air sensor activated
Yes
Air qual. fan comp.
No
Air quality-dependent fan compensation. Activation of analogue sensor input
Yes
Room humidity fan
comp.
No
Room air humidity-dependent fan compensation
Precondition: Sensor for room air humidity activated.
Yes
Outdoor temp. fan
comp.
No
Outdoor air temperature-dependent fan compensation.
Precondition: Outdoor air sensor activated.
Yes
